[GENERAL] Installing repmgr alongside PostgreSQL installed via EnterpriseDBinstaller instead of repositories? - Mailing list pgsql-general

Hello. First time poster, so please be gentle :)

I have a PostgreSQL 9.6 database cluster running on a standalone Redhat
7.2 (Maipo) server.

This may seem like a silly question. It probably *is* a silly question,
so apologies in advance.

PostgreSQL was installed using the "EDB Postgres Standard" installer
from EnterpriseDB -
https://www.enterprisedb.com/software-downloads-postgres - and installed
to a specific location - /db_<dbname>.  No repositories, nothing in a
'standard' place.

Output of pg_config is as follows:

BINDIR = /db_dbname/app/postgres/9.6.2-3/bin
DOCDIR = /db_dbname/app/postgres/9.6.2-3/doc/postgresql

I have now been tasked with putting repmgr onto this box and converting
it from a standalone to a multiple node setup (I have two additional
servers lurking in the background ready for use :) ).

Numerous articles on repmgr all seem to suggest it should be a
relatively simply operation once the software is in place. Register the
master. Clone standbys. Ought to be *relatively* straight-forward.

Unfortunately, I'm having problems at the first hurdle - putting the
software in place. We initially tried installing from the postgres
repository rpm - which insisted, of course, on installing PostgreSQL as
well as repmgr in /usr/pgsql-9.6. Obviously not the right place for it
given we're running our binaries from /db_dbname/app/postgres/9.6.2-3/bin

Is there a simple way to use repmgr from the package, perhaps by
copying/linking files from that location to ours? (e.g. copying/linking
some files from lib, bin, contrib, etc).

Or am I looking at having to compile the source? I'm told it should be
'simple' but I've not compiled much software from scratch on linux, so
I'm a bit nervous about the prospect. Any advice would be welcome :)

Basically, am I going to be stuck compiling from source or is there a
way around this?

Many thanks.

Martin.
